Warm your large soup pot over high heat. Add the olive oil.
When oil is hot, add the vegan chick'n. Stir around in oil to being the lightly browning process. After about 2-3 minutes, turn heat to low and add the water. Quickly cover pot with lid and let sit on low heat for a minute. This allows the water/steam to tendeize the chick'n a bit. For extra moist chick'n, steam a bit longer with more water. Turn off heat, remove lid and transfer your chick'n to your mixing bowl.
Add the vegan mayo, mustard, pepper, lemon and optional agave/maple to the chick'n bowl. Toss well until the chick'n is coated. If desired, you can add the mayo more to taste - using more or less of it. but it will give your sandwich a lot of flavor, so don't skimp!
Next, fold in the celery, optional scallions and parsley. You could also try dill or another fave herb. Fold until everything is combined and coated. And the last step is to salt to taste. You can also add more pepper if desired.
Transfer your chick'n salad to a sealed fridge-safe container and allow to chill for at least an hour (longer is better). You can easily make this the night before serving.
Serve chilled. I like to add my salad to a toasted pita, warmed french loaf or even just scoop it up with some crackers. Leftovers should be consumed in 1-3 days.
